8 Claims.

' This invention relates to apparatus for sparating stationery strips and carbon strips in conl tinuous-Iorm stationery after the usual writing operations have been completed. In some cases the stationery and carbon strips are connected together at one marginal edge by sewing or stitching, and the apparatus is designed to trim off the marginal portion of the assembly and thereby free the separate strips.

The primary object of the invention is to provide a simple and inexpensive apparatus/which will operate at a high speed and separate the parts in an orderly manner.

A further object of the invention is to provide winding spindles with friction drives so that the tension in each strip may be adjusted individually. This feature is very advantageous in starting the deleaving action.

Another object of the invention is to separate the strips without diverting them laterally in various directions, but instead to keep their edge portions in the same plane throughout the deleaving operation.

The invention is illustratedin preferred embodiments in the accompanying drawings, in

which- Y Figure 1 is a side elevational view of a machine embodying the invention; Figure 2, an end elevational view of the same; Figure 3, a top plan view; Figure 4, a fragmentary sectional view, taken as indicated at line 4 of Figure 3; Figure 5, an enlarged plan view of the cutter mechanism; Figure 6, a side elevational view showing a modied form of the device; Figure 6a, a modined arrangement of the stationery receiving part of Figure 6; Figure 7, an enlarged end view of one of the carbon-rewinding spindles; Figure 8, a plan View of the device shown in Figure 6; and Figure 9, a broken sectional View, taken as indicated at line 9 of Figure 8.

In the embodiment illustrated in Figure 1 5, inclusive, the frame has a belt housing IIl supported on vertical standards II mounted on a base I2. One of the standards is provided with a shelf I3 adapted to support a zigzag folded packet of stationery' which is to be deleaved by the machine. A plurality of winding spindles I4 have one end journalled in the housing I and are provided with smooth driving pulleys I5. While only three winding spindles have been shown, it will be understood that as many may be used as desired. A driving pulley I6 is also journalled in the housing I0 and is provided with a hand crank I1. An endless belt I8 passes around each oi the pulleys and an idling pulley I9, so that rotation ofthe crank I1 Will cause each of the spindles I4 to rotate in timed relation.

The strips of stationery in the assembly 20 are normally connected at one marginal edge by means of stitching, gluing, stapling, or the like,

and in order to separate each of the individual strips, it is necessary to trim oi! the binding edge 2i. This may be accomplished by means of a cutter mechanism 22 which, in the present form, comprises a circular saw 23 which is driven by a small electric motor 24 and operates in a groove in a guide-member 25. As best shown in Figures 1 and 3, a tensioning device 26 is provided to guide the stationery from the packet to the spindles. spaced rods 21 provided with lateral guide-members 28 andl carried by one of the rods 21 which is adjustably supported in the housing II). Thus it will be understood that by. turning the member 26 backwardly or forwardly, the tension in the advancing -strips may be regulated.

In starting this iorm of apparatus, the motor of the cutter mechanism is put in operation and the end of the assembled stationery is drawn through the cutter, so as to trim oil the edge 2I,

land through the. tensioning device 26. The lowermost stationery strip 'may be fastened to the hollow spindle Il by means of a paper clip, or in any other suitable manner, and a superposed carbon strip 29 is permitted to drop down into a Wastebasket beneath the machine. In like manner the second stationery strip from the bottom is secured to the next spindle and so on until all of the ends ofl the stationery strips are attached. The tension is then equalized in the stationery by manually rotating the spindles which will slip under the belt I8. After connecting up the stationery strips, it is only necessary to turn the crank I1 and all of the vstationery will be trimmed and wrapped up on the spindles from which it can be readily removed by slipping it out over the free end.

In the modification shown in Figures 6, '7, 8, and 9, the frame 36 has a plurality of compari;n

ments 3i in its base to receive the deleaved stationery strips. The superstructure 32 of the frame is Vinclined forwardly and downwardly and contains a plurality of earbon-rewinding spindles 33 which are all driven in timed relation by an electric motor 34, a belt 35, and a train of intermeshing gears 36. As best shown in Figure 9, each of the carbon-rewinding spindles has a slot 33a to receive the end of a carbon strip. The spindle is driven from one of the gears 36 by means offa clutch-head 31 which may be faced with anti-friction material 38 and is fixed to the spindle 33' by means of a set screw 39. A suitable compression spring 40 urges the clutch-head against the gear 36 and maintains a yielding contact therewith.

A-s the interleaved stationery 20 radvances over a guide-roller 4I, it passes through a guidemechanism 42 which is equipped at its front end with a presser member 43. The latter member serves to smooth out the stationery as it advances 'I'his device may comprise -a pair of means oi' a motor 4l. l

Instead of having each strip refolded separate- 1y, the strips that are not wound on spindles may be refolded simultaneously, in partially nested yrelation on a platform 20a, as illustrated in4 Figv lure 6a.

'I'he separate packs may later be .pulled out of interleaved relation without dimculty.

It will be understood that one marginal edge portion oi' vthe advancing stationery Vis kept in engagement with one side wall of the superstructure 32 as it advances, so that the stationery will be trimmed to an even width. The feed-mechanism is disposed about midway of the frame and comprises a pair of presser rollers 41 which are driven from the gears 36 by means of a train of idler gears 48. To start this form of apparatus, the stationery is led through the guide-mechanism and under the cutter head 45 so as to trim off the binding edge 2l. The lowermost stationery strip is vprojected down between the presser rolls 4l and the superposed carbon strip is secured to the winding spindle 33 by passing the end of the strip through the slot 33a. In like manner, the remaining carbon strips are attached to the winding spindles and the stationery is passed through the feed-mechanism. When the motor 34 is started, the stationery strips willthen be projected down into the compartments 3| and will refold into separate packets on the lines of folding and in the direction of the original pack.

It will be understood that the stationery, interleaved with one-time carbon, may come in roll form as well as in the zigzag folded packs illustrated. However, most of the stationery of this type has registering lines of weakening, through all the strips, between the sets of forms, and the strips are zigzag folded on those lines. As the stationery forms `usually have greater tensile strength than the carbon strips, it is preferable to have the feed-mechanism pull on the stronger strips. This may be reversed in either of the devices illustrated, however, so that in the machine shown in Figures 1 to 5, the carbon would be wound and the stationery refolded, orin Figures 6 to 9, the stationery wound and the carbon refolded.

'I'he foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom for some modications will be obvious to those skilled in the art.
